distribution?
3. (8 pts) Silver nitrite is known to react with primary alkyl bromides or iodides to form the corresponding nitro compounds (RNO2). However, it reacts with secondary and tertiary halides to form the corresponding nitrite esters (RONO). What are the most likely reasons contributing to this product distribution? R-X + AgNO RNO2 R = 1° only X = Br, 1 orRONO R = 29, 30 X = Br,

Question 1: draw a mechanism for each of the reactions.
Explain why the different amines create different products.
Question 2: Explain the product distribution. primary vs.
secondary or tertiary amines and their corresponding
products.
1. Draw a mechanism for each of the transformations (primary and secondary amines). Explain why the two different amines lead to different molecules. NaOH RNH2 + CHCI 1° amine R-NEC RNH + CHCI- 2º amine HNR2 2. What are some likely reasons that contribute to this...

When acyl halides (R?COX) or acid anhydrides (R?OC?O?CO?R) react
with primary amines (R?NH2) or secondary amines (R2NH), the
reaction yields an amide:
O || R?C?NR2
where R may be an alkyl group or hydrogen atom.
For example, propanoyl chloride
( O ||CH3CH2C?Cl)
reacts with ethanamine (CH3CH2NH2) to form
(O || CH3CH2C?NHCH2CH3).
The IUPAC name for the product isN-ethyl propanamide, as
it is formed from ethanamine and propanoyl
chloride.

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...

1. In both the sodium iodide
test and the silver nitrate test, why does 2-bromobutane react
faster than 2-chlorobutane?
Bromine is a better leaving group since it is a weaker base than
chlorine is.
2. a. Why does benzyl chloride react under both
SN1 and SN2 conditions?
Benzyl
chloride is a primary alkyl halide, hence reactive under SN2
conditions.
The
primary carbocation formed due to the departure of Cl- is
stabilized by the pi electrons in the benzene ring.
b. Why is...

Experiment 14 SN2: Synthesis of 1-Bromobutane Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as SNI (substitution, nucleophilie, unimolecular) and S2 (substitution, nucleophilie, bimolecular). Tertiary alcohols follow the Syl route, primary alcohols follow the S2, route and secondary alcohols can follow either path. Sth CyHe 81 CH?
